Letters Patent No. 111,536, dated February 7,1871.

IMPRVEMENT IN HYDRAULIC APPARATUS.

The Schedule referred to in these Letters Pate-nt and making part of thesame.

To all whom, it may concern;

Be it known that I ,GEORGE H1 HERRING, of Durand, in the county ofXVinnebago and State of Illinois, have invented a new and usefulImproveincnt in Apparatus for lifting or Forcing Water and otherliluids, of which the following is a full, clear, .and-exactdescription, reference being had to the accompanying drawing formingpart of this specification, and which represents a sectional elevationof an apparatus, constructed in accordance with my invention.

My invention, which l designate a self-acting forcepump, is mainlydesigned for forcing water in large or small quantities' to an altitudeabove the level of a running stream or fall by thepower of the latter asderived from the weight of the water in an accuniulative manner, bycausing y the stream to supply a tank capabie of rising and fallingunder the control of -a counter-balance, andso that the tank after' ithas received a certain load or charge of water overcomes thecounter-balance and descends and automatically discharges itself into awell or chamber that has arranged within or connected with it aforce-pump, the plunger of which is operated by the tank, said pumpdrawing the water from the well into its barrel and discharging ittherefrom alternately'by or,dur,ing the movement of thetank, as thelatter is controlled in its down-stroke by the weight of the waterwithin it, and in its `11p-stroke after having discharged its con-`tents by the action of the counter-balance.

Referring to the accompanying drawing- Arepresents a running st-reamv ortrough-receiving water from a head or fall, the height or depth ot'which may be. varied, or the .supply may be obtained` from a spring.

B is the power-tank or receiver, into which the water from the trough Aenters.

This tank is suspended by -a rope orchain, C, arranged to pass over apulley, D, and having attached to its opposite end a counterbalance,.E,which is of sufficient weight to elevate the tank, when empty, and withit the plunger F or working mechanism of the pump GL Said tank is fittedwith a valve., b, openingv inward, or that is kept closed while the tankis receiving water, and which is only required to be opened toward theclose of the down-stroke of the tank.

H is a well, in which the plunger G is placed, and

I, the discharge-pipe from the pump, leading torany desired height ordistance.

J is an overflow for surplus water from the well. .Vater accumulatingfrom the stream in the 1re# cciver B causes the'latter to descend,`andwith it the plunger F, so as to force out thc water from the pump-barrelup to the discharge-pipe I.

As the tank and plunger, however, approach the end of theird0wnstroke,'the valve l) `comes in conltact with a stop or lifter, c,which opens s'aidvalve Ycut ott from entering the tank by means of agate, d,

which is lifted oropened by the tank toward the close of the topstrokeof the latter, andremains open till the tank is sufficientlyloaded tovbegi'n its succeeding down-stroke.

In this way is an automat-ic action kept up without the aid ofwheels orcomplicated gearing, anda portion of the water furnished by the streammay be forced to any desired height above the level of the Vstream,tliisresult, too, being irrespective of the head or fall variation ixrwhichwill only affect the velocity at which the apparatus 'works orquantityl'of water delivered in a given time.

The pulleyD it is preferredto make of such a shape that the tank willdescend with an accelerated motion, so as to insure its descent andopening cf the valve b, and said accelerated motion afterward madeavailable, through the' operation of thccounter-lmlance, to carry up thetank with suticient force to open thc gate d for a fresh suppl y to thereceiver or tank. l i

In cases where a high head ot' water' is available, then instead of thepump-,plunger being connected in a direct manner by `1'od with thepower-tank, the connection may be made through the intervention of alever.

Likewise, it" desired, two pumps may be used with a power-tank to'eacl1,and a beam or "lever connecting them, so that they act in common,and alternately in reverse directions, and operate each as acounter-balance to the other, thereby dispensing with a separatecounter-,balance or weight.

XVhat is here claimed, and desired to be secured by Letters Patent, is fl. A pump, the piston of which is operated in its down-stroke by theweight of water in a tank connected or supported on the piston-rod, saidtank being provided with a valve' so arranged as to be opened by comingin contact with a projection, c, to canse said tank to discharge itscontents into va Well or reservoir, in combination with acounter-balance, by

which said piston is raised when the contents of the Y tank aredischarged.V

2. Combination and arrangement of the tank ]3, provided with avalve, bthe pump G, and .its` piston F, cord or' chain C, pulley D,counter-balance E, and flume-gate d. for-operation as herein described.
